d) The yield point is the point on a stress-strain curve that indicates the limit of elastic behaviour and the beginning of plastic behavior. In this case, the yield point occurs at a stress value of 80. Determine the corresponding strain value at the yield point. In any relevant method, use a stopping criterion of 0.05%. e) The ultimate strength is the maximum point on the stress-strain curve. This corresponds to the maximum stress that can be sustained by a structure in tension. Compute the ultimate strength point of the polymeric material (strain value that gives maximum stress). In any relevant method, use a stopping criterion of 0.05%. f) Determine the absolute error between the calculated maximum concentration and the highest experimental data.

d) The yield point is the point on a stress-strain curve that indicates the limit of elastic
behaviour and the beginning of plastic behavior. In this case, the yield point occurs at a
stress value of 80. Determine the corresponding strain value at the yield point. In any
relevant method, use a stopping criterion of 0.05%.
e) The ultimate strength is the maximum point on the stress-strain curve. This
corresponds to the maximum stress that can be sustained by a structure in tension.
Compute the ultimate strength point of the polymeric material (strain value that gives
maximum stress). In any relevant method, use a stopping criterion of 0.05%.
f)
Determine the absolute error between the calculated maximum concentration and the
highest experimental data.
